The HeatMiner® visual data mining technology developed by Agience Oy Ltd can visualize the distribution of colors in a given image as a three-dimensional RGB heatmap. HeatMiner uses red, green and blue color levels of pixels as (x,y,z)-coordinates and visualizes frequent RGB-combinations as a colorful 3D shape. This gives the correct overall impression of the color distribution, unlike when viewing red, green and blue histograms separately which has been the common practice in photography.
